I would not. I don't know about the other cars but thinking about the Porsches, the PCCBs are quite expensive and for fairly normal street driving I don't think they would be necessary. I don't race, but even if I did, I don't think I still would get them since I believe that it's pretty easy to mess up the rotors when getting off-course on gravel for example. And again, the replacement is very expensive. My guess is that the advantages of the PCCBs would not be worth the cost.
